My Question or Issue

The track recommendation endpoint (/v1/recommendations ) returns invalid values for the album_type of the album of the returned tracks.

According to the docs, the album_type value should be in lower case, and allowed values are "album", "single", "compilation". For this endpoint (and seemingly only this one endpoint) the values are returned in upper case instead.
